Not sure why this isn't accepted.I have description() taking no values outputting ->String & I used string interpolation

? not sure whats wrong with this.......

structs.swift 
struct Tag {
    let name: String
}

struct Post {
    let title: String
    let author: String
    let tag: Tag

    func description() -> String {
        return "\(title) by \(author). filed under \(tag)"
    }

}


let firstPost = Post(title: "iOSDevelopment", author: "Apple", tag: Tag(name: "swift"))

let postDescription = firstPost.description()

It's all just fine except that the tag you're interpolating should be tag.name. Take a look at the string to be returned.

return "\(title) by \(author). filed under \(tag.name)"
